My electric range is positioned in an alcove, the only possible place for it, where the back and one side of the range are about 1 inch from the wall. There is a formica backsplash around the walls. The formica at the side wall seems to be buckling away from the wall in places. There is also a brown spot where it may have been burned. Should I remove the formica, and is there any simple covering that would protect that wall from the cooking heat?
